It's the end of the holidays for Mark, Annie and Pudding (real name: Derek). They've spent the summer in a cottage on the edge of a forest in the countryside, but they haven't had any really exciting adventures to tell their classmates back at school... Until, on their final visit to see the Frog King of a nearby pond, they find a frightened young girl crying in the woods. The curiously named Macadamia tells them she has lost Clementine, and so the three children set out on a quest to find her. But they are not the only ones looking for Clementine, and a storm is approaching, bringing with it a night full of surprises...
